Created July 14, 2021 14:01
Javascript function (in AWS Lambda form) that crashes ever other minute. Useful for testing Alarms.
exports.handler = async () => {
// causes a crash every other minute by returning an invalid value
return (new Date().getMinutes() % 2) ? () => {} : 1;
};

Traverse a Javascript object. Particularly useful for dump(this) to grab everything.
dump = (target, match_re, depth, seen) => {
if (depth === undefined) depth = 0
if (seen === undefined) seen = [target]
Object.keys(target).forEach((i, idx) => {
value = target[i] ?? "null";
isObject = (value === Object(value));
